摘要	Polyaniline nanofiber(Nano-PANI) modified graphite foil(GE) (Nano-PANI/GF) was prepared by electrochemical polymerization of aniline on GF electrode. The polymer on the modified electrode Nano-PANI/GE was characterized by FTIR. The morphologies of the modified electrode were investigated by SEM. The Nano-PANI/GF electrode made through cyclic voltammetric scans in a solution of 0. 1 mol/L aniline and 1. 0 mol/L HCl showed good electroactivites in 0. 1 mol/L phosphate buffer solution( pH = 6. 9). The electrocatalytic properties of the modified electrode toward ascorbic acid oxidation were studied through cyclic voltammetry and potentiometry. The current for ascorbic acid oxidation on the modified electrode at 0. 2 V showed linear response to the concentration of ascorbic acid in the range of 1. 7-2. 0x10(3) mu mol/L. The detection limit of ascorbic acid on the modified electrode is 1. 7 mu mol/L(S/N =3).
